June 14, 1932. J. VAN BUREN CONTAINER Filed Jan. 17, 1929 INVENTOR JZ/ml2 flare/1 Patented June 14, '1932- PATENT oFncE JOHN VAN BUREN, OIBROOKLYN, NEW YORK CONTAINER Application filed January 17, 1929. SerialNo. 333,144.

This invention relates to containers.

It is very diflicult to pack granular or flakey material, such'as soappowder, soap flakes, cereals, etc., in carboard containers in 6 such amanner that the material will not leak out of the container. This can beovercome by packing the material first in a bag and then packing the bagin the container. This, however, increases materiall the expense ofpackaging. The leakage rom cardboard containers usually takes place atthe ends or at the portions where the container is closed.

This invention has for its salient ob ect to provide a container orcarton so constructed and arranged that the material therein will I notleak out at the sealed or glued ends or other portions thereof.

Further objects of the invention will appear from the followingspecificat on taken in connection with the drawing, which forms a partof this application, and in which Fig. 1 is perspective view of acontainer or box constructed in accordance.w1th

the invention and having the ends closed and sealed-5 a Fig. 2 is aperspective view similar to Fig.

1 but showing the ends open;

Fig. 3 is a perspective view showing the two parts of the containerseparated; 3% Fig. iis a plan view of one of the blanks I used to form acontainer; and I Fig. 5 is a plan view of the other blank used to tornia container. e

The invention briefly described consists of a container formed in twosections which are secured together and are provided with flaps adaptedto fold over the end of the container and to secure the material packedtherein against leakage. The container has end tabs adapted to folddownwardly toward each other from the sides and also has end flaps atthe front and back faces thereof adapted to fold down against the sideend flaps. In addition to these flaps the container has ears which aresecured to the ends of the sides of the container. I

Further details of the invention will appear frorn the followingdescription.

. The container comprises a pair of sections A and i3. Section A has acentral portion '10 which is adapted to form the front or back of thecontainer, as the case may be, and has longitudinal fold lines 11 and 12and side tabs 13 and 14 extending beyond the fold lines 11 and 12. Atthe two ends of the cen; 86 tral portion 10 are formed flaps 15 and 16which are joined to the central section on fold lines 17 and 18. Theflap 16 has formed at the ends thereof ears 20 and 21, fold lines 22 and23 being formed between the flap 16 0 and the'ears 20 and 21. Cornerpieces 25 and 26 are formed at the ends of the side tabs 13 and 14.

Section B of the container has a central portion 30 adapted to form theback or front of the container, main flaps 31.and 32 being formed on theblank at the ends of the sectron B and being joined thereto on foldlines 33 and 34. At the sides of the central portion 30 of the'blankthere are formed side sections 35 and 36 having end flaps 37 38, 39 and40, as indicated on Fig. 5. Fold lines 41 and 42 are provided betweenthe central portion 30 of the blank and the side sections 35 and :36 andthe fold lines 33, 34 extend across Elie uncture of the side sectionsand the end aps.

Before the two sections of the container are secured together, the tabsand flaps are folded alon the fold lines in the manner 30 shown in -ig.3. When the sections or blanks have been so folded, the side tabs 13 and1d are secured to the sides 35 and 36, as shown in Fig. 2. After thishas been done the corner pieces 25 and 26 are secured to the 35 endflaps 38 and 40, and these flaps are folded inwardly. Then the flaps 15and 32 are then folded inwardly and are secured to each other and to theflaps 38 and 40. The flaps and tabs just mentioned can be efi'ectivelysecured to each other by inserting a block within the container andexerting pressure as these parts are being secured. However, it is moredifficult to secure the other end of the container against leakage,since the container is filled with any desired material and after it isfilled the end flaps 37 and 39 must be folded inwardly and the flaps 16and 31 must be secured thereto. It is practically impossible to exert apressure in a direction opposite to the downward pressure to secure the-flaps'. For this reason a double safeguard against leakage has beenprovided. The end flaps 37 and 39 are first folded inwardly, asdescribed and adhesive is applied thereto, whereupon the flap 31 isfolded downwardly and is held in engagement with the end flaps ,37 and39.; Adhesive is then applied to the I outer surface of the flap 31 andthe flap 16 is folded downwardly intoengagement therewith. The ears 20and 21 arethen secured against the end portions of the sides of thecontainer, as shown in Fig. 1.- It will be wardly folding rectangularendflaps of the width of the side sections, adapted to maintain the shapeof the carton, and another piece forming a back or front and a pair ofinwardly -foldin main flaps, the edges of one of said main haps beingextended to form ears projecting from the sides thereof adapted to befolded against and to be afiixed to the side sections of the firstmentioned piece, and

side tabsconne'cted with the side sections of the first mentioned piece.

' JOHN V-AN BUREN/ obvious that the provision of flaps 37, 39, 1

31, 16, 20 and 21 effectively prevents any leakage from the corners ofthe box.

' Although one specific embodiment of the invention has beenparticularly shown and described, it will be understood that theinvention is capable of modification and that.

changes in the construction andin the arrangement of the variouscooperating parts may be made without departing from the spirit or scopeof the invention, as expressed in the following claims.

What I claim is:

1. A container having front and back por- I tions and side sections,inwardly folding main flaps extendingfrom the ends of the front and backportions, and end flaps extending from the ends of the side sections,

side tabs interconnectingthe side sections 5 with a front or backsection, extensions of said side tabs adapted to be aflixed to, the endof one of said main flaps being extended to form ears projecting fromthe sides thereof, side tabs and corner pieces, sa1d corner pieces beingadapted to be affixed to the end flaps at one end of the side sections,and said ears being adapted to be aflixed to the other end of the sidesections. I

3'. A- container having front and back portions and side sections,inwardly folding main flaps exten'dingfrom the ends of the front andback portions, and rectangular end flaps of the width of the sidesections extending from the ends of the side sections, side tabsinterconnecting the side sections with a'front or back section, andears, projecting from one of the main flaps adapted to be affixed to theside sections.

4. A container constructed ofone piece forming a front or back, inwardlyfolding mainflaps and side sections, similar ends of both side sectionsbeing extended to form in-v
